STORM SASH OPERATING MEANS Filed Oct. 25, 1957 Patented May 17, 1938 UNITED. STATES PATENT OFFICE 12 Claims.

()ne object of my invention is to provide an operating means for storm sashes and the like which is simple, durable and comparatively inexpensive to manufacture.

A further object is to provide an operating means for storm sashes which, through movement of the upper sash accomplishes the result of unlocking and opening the storm sash when the upper sash is opened to admit air for ventilation, the operating means effecting closing and locking of the storm sash when the upper sash is moved from open to closed position.

A further object is to provide articles of hardware to serve as an inter-connection between a storm sash and the upper sash of a double hung window whereby the sliding operation of the upper sash opens and closes the storm sash.

Still a further object is to provide such articles of hardware especially designed so that they may be easily and quickly attached by a carpenter.

to the usual double hung window and storm sash to thereafter effect operation of the storm sash by movement of the window.

Still a further object is to provide hardware including pivoting means for the lower end of the storm sash, lock means for the upper end thereof and operating means for the central portion thereof, the pivoting means being associated with the sill of a double hung window and the lock means and operating means being associated with the upper portion and lower rail respectively of the upper sash of the window.

With these and other objects in view, my storm sash operating means consists in the construction, arrangement and combination of the various parts thereof, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawing, in which:

Figure 1 is avertical sectional view through a window showing my storm sash operating means associated therewith and the storm sash and upper sash closed. a

Figure 2 is a similar sectional view of a portion thereof showing the parts in a different position with the upper sash slightly lowered.

Figure 3 is a similar sectional view showing the parts in still a different position, the upper sash being further lowered and the storm sash being open.

Figure 4 is an enlarged sectional view on the line 44 of Figure 1 showing an inside elevation of a portion of the hardware I use.

Figure 5 is a perspective view of one of the elements of the hardware shown in Figure 4; and

Figure 6 is an enlarged sectional view on the line 6-6 of Figure 1 showing another portion of the hardware which I use.

On the accompanying drawing I have used the reference numeral Hi to indicate the sill of a win dow. The head jamb thereof is indicated at H and the side jamb at l2. In the window frame, upp.-r and lower sashes US and LS are slidably mounted.

A storm sash SS is mounted in the window frame. The three sashes thus far referred to are of standard construction. For pivoting the storm sash SS relative to the sill I0, I provide a pin l3 driven into the lower edge of the storm sash, the pin projects into a. socket l4 formed in the sill I 0. Cgacting brackets l5 and iii are mounted on the storm sash and blind stop I! of the window frame respectively adjacent the pin l3. -In a narrow storm sash one of the pins I3 is sufficient, while in a wider sash two or more of the pins may be used. A pair of the brackets 15 and I5 are provided at each side of the window frame although the drawing shows only one side of the frame.

In applying the brackets l5 and 16 to the storm sash and window frame, the brackets l5 are first secured to the lower rail of the storm sash adjacent the bottom corners thereof as shown in Figures 1 and 6. The brackets 15, it will be noted, have flanges I 5a terminating in hooks 15b, The brackets l6 have hook fingers Isa adapted to fit over the flanges l5a after the brackets l5 are mounted in position and the storm sash is mounted in the window and closed. The brackets l6 are attached to the blind stop I! in position to confine the flanges l5a without, however, binding against them and the hooks [5b serve as stops in an excessively open position of the storm sash which position, however, is not assumed during normal operation.

Coacting lock elements 18 and I! are provided on the storm sash and upper sash respectively. These have inclined arms normally engaged with each other as shown in Figure 1. In a window installation there is a pair of them for each stile of the upper sash or one pair for each side of the sto rm sash SS to insure a substantial lock therefor.

A housing 20 is provided which may be countersunk in the stile of the storm sash as shown in Figures 1 and 4 or designed so that it can be mounted on the surface thereof if desired. The housing 2|] is provided with a cover plate 2 l. The housing and cover are secured in position by screws 22. Within the housing 20, a plate 23 is provided. It is channel-shaped and the flanges 2 thereof are pivotally mounted on a pin 25 extending from side to side of the housing 20. The plate 23 is biased to the position shown in Figure l by a spring 26.

On the lower rail of the upper sash I mount a pair of angle brackets 21 and 28. These pivotally support the upper end of a link L. The link L as shown in Figure 5 may be formed of flat bar stock. The link L is twisted as indicated at 29 and terminates in a T-head 30 bent at right angles to the general plane of the link. Adjacent the T-head, the link is provided with a pair of notches 3| which makes this portion of the link less in width than the width of a slot 32 formed in the cover plate 2| of the housing 20. The T-head 30 is arranged inside the cover plate and thus I provide a sliding, but non-disengageable connection between the link L and'the storm sash SS. The link L is screw-threaded as indicated at 33 to receive a set screw 34. A look nut 35 is positioned on the set screw 34.

Practical operation In the operation of my device, after the hardware is installed on the window and its storm sash, the parts are normally in the position of Figure 1 when the window is closed. The upper sash US may be lowered which initially unlocks the storm sash by separating the lockelement l9 from the lock element l8 as shown in Figure 2. During the lowering of the upper sash, the T- head 30 of the link L slides along the plate 23 causing it to pivot on the pin 25 against the action of the spring 26. Slightly lower than the position shown in Figure 2, the T-head 30 will engage the bottom wall of the housing 20 and since the link L is extending at an angle to the vertical, any further lowering of the upper sash will tend to swing the storm sash outward.

As the upper sash is thereafter lowered toa further degree, for instancaas shown in Figure 3, the storm sash will be swung further open so that ventilation is provided through the opened storm sash and the upper open sash. If additional ventilation is desired, the lower sash can also be opened.

Due to the spring 26 urging the plate 23 to the position shown in Figure 1, after the T-head 30 passes the lower end of the plate during the lowering operation, the T-head will hook under the edge ol the plate as shown in Figure 3. Accordingly when the upper sash is subsequently raised the link L will pull inwardly on the storm sash and just prior to the position of Figure 2 being assumed, the set screw 34 will engage the plate 23 to swing it to a position where the T-head 30 will unhook from it. This arrangement thereby permits further sliding of the sash for the purpose of locking the storm sash in closed position as the T-head 30 can then slide vertically in the slot 32 without pulling up on the storm sash due to being hooked under the lower edge of the plate 23.

The set screw 34 i; made adjustable so that proper unhooking of the T-head 30 is effected during the raising of the upper sash. The lock nut 35 retains the set screw in properly adjusted position.

The type of hardware which I have provided at the center of the storm sash, permits movement of the upper sash for locking and unlocking purposes without effecting swinging movement of the storm sash. During the closing of the storm sash, it is necessary to first swing it inwardly and then lock it by the final closing of the upper sash. For this reason a simple lost motion connection between the upper sash and the storm sash will not suflice and I therefore provide the type of hardware disclosed at the center of the storm sash to accomplish the desired results. Thus I am able to use the upper sash as a means to lock and unlock the storm sash as well as swing it to opened and closed positions.

Some changes may be made in the construction and arrangement of the parts of my storm sash operating means without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims, any modified forms of structure or use of mechanical equivalents, which may be reasonably included within their scope.
